Application led April 13, 1925.

My invention relates to improvements in vibrators especially adapted to be secured to the fingers of the operator, the object of the invention being to provide a simple and eliicientconstruction of this character which may be readily adjusted to fingers of different sizes; in which the extent of the vibration may be readily adj usted; and which inay be readily and efficiently attached to or detached from a flexible shaft for operating the saine.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this` specification, and in which,

Fig. 1 is a side view of the vibrator;

Fig. 2 is a rear end view of the same;

Fig. 3 is a front end view of the same;

Fig. 4 is a face view of an `adjusting wheel employed in the construction;

Fig. 5 is a perspective view of a locking spring emplo ed in the construction;

Fig. 6 is a ongitudinal vertical section of the vibrator;

Fig. 7 is a section taken on line 7-7 of Fig. 6;

Fig. 8 is a section taken on line 8-#8 of Fig. 6;

Fig. 10 is a section taken online'10,-10 of Fig. 6.

The preferred forin of construction as illustrated in the drawings comprising a cylindrical easing 11 provided at its rear end with a central shaft bearing 12 arrangedv to receive a central operating shaft 13 as shown. The casing 11 is provided with a rearwardly extending central sleeve 14 into which said shaft 13 projects where said shaft is provided with the usual socket and slot arrangement for attachment to the usual flexible shaft 15 arranged in the usual shaft casing or sheath 16 adapted to be inserted in the sleeve 14 in the usual way to engage and drive the shaft 13. The shaft casing 16 is provided with an annular groove 17 adapted to receive the inwardly turned end 18 of the limbs 19 of a coiled lock spring 20. The lock spring 2() consists of a spring wire Serial No. 22,526.

coiled as shown and having its ends extended to form parallel limbs 19 adapted to embracethe sleeve 14, the inwardly turned ends18 extending through openings in said sleeve to engagethe groove 17 to lock the flexible shaft in the sleeve but pern'iitting its ready removal when desired. 11n annular groove 21 is provided in the sleeve A14 to receive the limbs 19 as shown in Fig. 10 and whereby the spring 20 will normally he locked in radiating position and vibration thereof prevented. Obviously, by-swinging the spring 2O with the ends 18 as pivots, the sides of the groove 21 will operate-asV cani members to spread said limbs 19 and thus release the shaft 16 when desired. Likewise when it is desired to insert the shaft, by

'swinging the spring 20 the ends 18 may be withdrawn to facilitate such insertion yas will be readily understood. i

At the forward end the casing 11 is provided with a removable screw threaded cap 22 having central bearings 2S to receive the forward end of the shaft `13, and whereby said shaft is removably held in place in said casing. A segmental vibrating weight 24 is provided with a central reduced hub portion 25 secured to the shaft 13 by 'means of a pin 26, said weight 24 being arranged to revolve within the casing 11 as indicated. Cooperating with the fixed weight 24 is an adjustable weight 27 of substantially 'the saine size, said adjustable weight `27 being provided with separated hubs 2S loosely engaging the shaft 13 on opposite sides of 'the hub 25. The adjustable weight 27 Ais provided with a slit 29 spanned by a clamping screw 30 and whereby the weight 27 may be clamped to the hub 25 in adjusted'positions. 'By this arrangement it will be observed that the weight 27 may be readily adjusted on the shaft 13 either to oppose, partially oppose or cooperate with the weight 24. Obviously, when the weight 2'? is adjusted into juxtaposition relatively to the weight 24 as shown in Fig. 7, the two weights, being equal, balance each other and there will be little or noy vibration when shaft 13 is rotated. But when the weight 27 is adjusted angularly from this position such balance is destroyed and when the weight 27 is adjusted to a position closely adjacent te the weight 24 the entire weight tien cooperates with the weight '24 te produce vibrations oit the shait 13. In intermediate ,positions the Weight- 27 tends to counteract ipartiallythe efl'ect ot the weight 24 and thus the extent of the vibrations may be adjusted and controlled as desii'ed.

A clamping bracket *3l lis Vsecured uo #the undeiside of the casing 11 and sleeve 14, said clamping bracket being provided `with fixed clamping bars 32 .and 32. The .bar 3L- is secuied to the underside of the sleeve 14 by vnieansot r.an integral central lug 34 and ithe .bar 32 .is secured to the underside `off the casing 11 by means of the integral lugs 33, .there .being .anopen space between shown. The clamping bars 32 and 32 are provided :with ,padding in the ,forni olf .strips of :sponge rubber, said strips being secured in jplace by .means vof hollow .rivets 36, ,said rivets .3G ibeing slic'lable .through openings in the corresponding clamping bar and `whereby yielding o'fttlie ,padding is facilitated. A sliding bar 3T is mounted to slide .radially in .the (bracket 3,1 :and carries tat its nlower .end la clamping yoke 38 cooperating .with the clamping ba-rs 32 ,to

clamp :the `fingers of .the Aoperator .to secure the .vibrator .in ,position .on the iback .of .the hand. The ysliding Vbar .37 .is ,provided at its inner end with ,a ilng or Vprojection `39 .engaging .an .eccentriccam ,groove 40 in the inner ,faceof a lnurled kadjusting Wheel 41 Aas ,best shown-in Rigs. `6 and 8. The adjusting ,Wheel 41 is rotatably mounted on the sleeve .1.4 ,being:provided at onel side with .anfentry notch .42 ,adapted 4to pass overthe .lngg34 in placing said Jadjlisting yWheel in` .;gaging .the notch42 ,in ,the Wheel /41 and 4thus .lockinw the s .niine 2,to ,the .Wheel ,41 and e ,i o

permitting the l.ready assembling ofthe ;paits. .The spring 43 `is lprovided .with dia- ;nietricallvzarranged ,l/fslia )ed 'beadsor rojections 46 ,arranged .to engage radiating Anotches 47 ,inthe inner ,face ot' a lock washer 48, said lock .Washer being arranged to fit Aover vthe sleeve 14 and ,provided -with a notch .49 embracing the inner portioiroffthe `-lug 3,4.and lto which lit issecni'ed by means .ot'aclamping screw ,50. By iis arrange .ment .the fparts will rbe readily locked lin vposition on .the .sleeve 14 and the bracket 31 and imay .be readily Vremoved by vremoving the lock Washer 48. When the adjusting wheel 41 is turned in adjusting the clamp to the lingers ot the operator the beads 43 on the spring will be :caused to snap lfrom one pair of' notches 47 to another thus i'eleasa'bly locking the adjusting wheel 41 in .ofthe hand of the operatorby'eiigagingtlie Iiiiiger c laiiip with v*the middle 'and third iiigers, and, -Avhenattaelied tothe flexible shaft, uillcaufte the hand to vibrate. Itisapplied tothe ,face or scalp by simply resting oi' rubbingthe fingers or hand over the tace or scalp, `the vibrations caused by the imbal- ,aiiced Weight on vthesha'ft 13 being thus iinparted -to the 'face or scalp or other portion of the Vbody to `which thehaiid 'is applied.

While I have illustrated anddesciibed 'the ,preferred jf'orm of construction :tor carrying .my ,invention into effect, this is 'capable of variation and modification yWithout departing lfrom the spirit .of "the invention. "I, therefore, do not Wish to *be limited to the precise details of construction setfortli, but desire yto avail myself of'such variationsand modifications as. come Within the scope 'of the appended claims.
